[UserNameGoesHere]

Consider this a request to have them mutually remove, and to have the removee be sent a message similar to the "You have a new friend!" except "You have been removed from so-and-so's friends list" or such.

This wouldn't have worked as a random thought since the type of people to whom it is directed likely wouldn't have seen it, since those are sent only to people who currently have you on their friend's lists.

And I view it mostly as a way for people to advertise others' profiles, so if you want me to advertise your profile via friends list you better be doing the same.
